T0 all whom it may concern,.-

Be it known that we, EDWARD HUBER and JACOB W'. MILLER, citizens of theUnited States, residing at Marion, in the county of Marion and State ofOhio, have invented certain new and usefulImprovements in SwingingStraw-Stackers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The invention has reference generally to apparatus for stacking straw.More particularly, however, it relates to the novel construction of themechanism employed4 for automatically swinging from side to side thestacker proper, whereby an even distribution of the straw is obtained.

In building straw-stackers heretofore it has been the custom to arrangea turn-table upon a wheeled frame of any desired construction or uponthe rear of the thresher-frame and to mount upon said turn-table thestacker, employing such means for actuating the turntable as would causethe stacker to automatically move' from side to side a limited distance.This general construction we have embodied in the invention hereinafterdescribed; but the particular construction and combination of partswhich make up the stacker is 'a departure from the present state of theart. This is especially true with respect to the shifting mechanism; andour invention consists inthe novel construction of the actuatingmechanism for the turn-table, which will be more fully hereinafterdescribed and shown in the drawings, in which- Figure 1 is a sideelevation of our improved stacker. Fig. 2 is a rear elevation thereof.illustrating the driving and shifting mechanism. Fig. 3 is a plan view,partially broken away, further illustrating the shifting devices. Fig. 4is a detached view of the bevelgears in section; and Fig. 5 is a sectiononl line Fig. 4, looking in the direction of the arrows, illustratingthe arrangement of the clutch mechanism.l

The invention will be shown anddescribed as used in connection with thetype of strawdischarging apparatus known as pneumatic straw-stackers. Wedo not limit ourselves to this type, however, as it is obvious that anydischarging apparatus may be mounted upon the turn-table, which isactuated by the mechanism hereinafter described.

- The reference-letter A represents any suitable supporting-frame uponwhich the stacker and its parts are adapted to rest, and B adelivery-pipe secured within said frame, adapted to communicate with thethresher proper. A turn-table D of any desired construction is mountedupon the framework and has bearings upon the same,`so as to admit ofrotation, said turn-table being providedwith a plurality of gear-teethupon its periphery and held in its proper position upon the framesupportby means of the retaining-plates E.

4These plates are securely bolted tol the supporting-frame and carry attheir ends proj ections a, which extend over a portion of the circulariiangehon the interior of the turn-table. Rigidly attached to the tableby means of braces F andG is the stacker proper, I-I, one end of whichcommunicates with the delivery-pipe B.

The actuating mechanism for the turn-table is of the followingconstruction: A drivingshaft I is mounted in suitable bearings I,secured to the frame-support, and carries at one end and iixedly securedthereto a drivingpulley J.' Upon its free end the shaft is adapted tocarry two bevel-gears K and L, loosely'sleeved thereon, and between saidgear-wheels a double clutch M, rigidly attached thereto. Upon a shaft N,journaled in bearings in the frame A and at right angles to thedriving-shaft I, is a bevel-gear O,

adapted to mesh with the gears K and L. On

the free end of the shaft Nisarranged a wormgear I), adapted to meshwith the gear-wheel Q, having bearingsl in the main frame andl havingrigidly attached upon the same a gearpinion R. Mounted upon the frameina manner similar to the gear Q is aNgear-wheel S, which meshes with thegear-pinion R and has iiXedly secured upon the same a gear-pinion T, thelatter pinion being adapted to mesh with the gear-teeth upon theperiphery of the turn-table. The driving-shaft I, beingloosely journaled in the bearin gs or boxes l,is capable of a limited lateralmovement derivedfrom the shifting device hereinafter described, whichpermits the clutch M to engage alternately with the gears K and L.

IOO

The clutch consists of an apertured block adapted to be sleeved upon theshaft and provided with a wedge-shaped lug CZ, said lug being adapted toreceive a set-screw or bolt e, which rigidly secures the clutch to theshaft. Upon the bevel-gears K and L, as plainly shown in Fig. 5, arearranged blocks f, eX- tending a slight vdistance above the faces of thegear-wheels, which form a bearing against which the lug CZ of the clutchproper abuts when the shaft is shifted through the gearwheels. Theseblocks f are shown in section in Fig. et.

are of the following construction:

A shifter U is mounted in the projecting arms of one of theretaining-plates E, located upon the supporting-frame at a point abovethe driving-shaft I. The arms of the plate form a bearing for theshifter, upon which the the latter is enabled to be moved in the are ofa circle. The shifter consists of a curved metallic bar g, provided withextensions projecting from either side of the center, the inwardprojection having a horizontal slot h and the outwardly-projectingportion carrying an upright lug t', the lug being arranged in the pathof pinsj and j', which are inserted in apertures ,j2 in the rim of theturn-table. Secured to the frame A beneath the shifter is adownwardly-extending supporting-bar 7a. At the lower end of this bar andpivotally attached thereto is a shifting lever Z, which lever projectsupwardly, the free end of which is adapted to extend through the slot71, in the shifter, as plainly shown in Figs. 2 and 3. Adj ustablysecured to the driving-shaft I are the collars m and a, and interposedbetween the collars is a shifting block 0. The block is adapted to slideupon the shaft and is provided with an apertured lug p, through whichaperture a pin q on the shifting leverrextends. The shifting lever Z ispivoted to a spring-lever r by means of the link s, the latterleverbeing pivoted in turn to the frame A at t. w is a bracket apertured atthe center, through which aperture a headed rod t is adapted to pass,one end of which rod is attached to the free end of the spring-lever r.Between the bracket and the headed end of the rod is interposed a spiralspring m.

The parts having thus been described and shown, their operation is asfollows: Motion e beingcommunicated to the drive-pulley J, the

It will be seen by this construction that our clutch is exceedinglysimple and is further movement of the table the pin will carry theshifter along until the shifting lever Z comes in contact with the same.The lever will then be driven to one side, carrying with it the shiftingblock o. This movement of the shifting lever causes the spring-lever r,through the link connection, to rise, thereby compressing the spring Thestops or collars m and a are arranged at `such distances from each otherthat the lever-arm will pass the center in either direction at the timethe shifting block strikesl the same. Upon further movement-of the tablethe shifting block will be forced against the stop a until the clutch Mis withdrawn from its engagement with the bevel-gear K. At this momentthe shifting lever being but slightly over the center the spring willcause the lever fr to throw the clutch immediately into engagement withthe bevel-gear L, thereby reversingthe movement of the table. Thecollars 'm anda, bcing adjustably secured to the `driving-shaft, can beset at any desired distance from each other, so that the proper throwwill be obtained for the shifting arm.

Having thus described our invention, what we claim, and desire to secureby Letters Patl. In a straw-stacker, the combination with a mainsupporting-frame and a turn-table mounted thereon, of a driving-shaft, adouble clutch secured thereon, a plurality of gearwheels loosely sleevedon said shaft, a gear connection between the gear-wheels and the turntable, and actuating mechanism for shifting the shaft through saidgear-wheels, whereby said double clutch engages with a different gearand whereby the direction of rotation of said turn-table is reversed.
